Summary
Posterolateral corner (PLC) knee injuries are often missed, leading to instability and reduced quality of life. A new arthroscopic technique fixes the popliteus tendon to the tibia, restoring stability and improving knee function.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Knee Biomechanics
Background:
- Posterolateral corner (PLC) knee injuries frequently go undiagnosed.
- Untreated PLC injuries cause posterolateral rotational instability, diminishing patient quality of life and knee biomechanics.
- Existing surgical options for PLC injuries include open and limited arthroscopic procedures.
Purpose of the Study:
- To present a novel arthroscopic technique for repairing posterolateral corner (PLC) knee injuries.
- To address external rotational instability caused by PLC damage.
- To utilize the native popliteus tendon as a vascularized graft for reconstruction.
Main Methods:
- Development of an arthroscopic technique involving an additional midlateral portal on the lateral knee.
- Fixation of the popliteus tendon to the tibia to recreate a static stabilizer.
- Focus on restoring stability against external rotational forces.
Main Results:
- The described technique effectively recreates a static stabilizer for the posterolateral corner (PLC).
- Fixing the popliteus tendon provides a native, vascularized solution for PLC reconstruction.
- The approach aims to mitigate external rotational instability.
Conclusions:
- This arthroscopic technique offers a viable method for addressing posterolateral corner (PLC) injuries.
- Utilizing the popliteus tendon provides a biological and stable reconstruction.
- The procedure holds potential for improving outcomes in patients with posterolateral rotational instability.

Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters.

Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

The time response of a linear time-invariant (LTI) system can be divided into transient and steady-state responses. The transient response represents the system's initial reaction to a change in input and diminishes to zero over time. In contrast, the steady-state response is the behavior that persists after the transient effects have faded.
The stability of an LTI system is determined by the roots of its characteristic equation, known as poles. A system is stable if it produces a bounded...

In mechanical engineering, the stability of systems under various forces is critical for designing durable and efficient structures. One fundamental way to explore these concepts is by analyzing systems like two rods connected at a pivot point, O, with a torsional spring of spring constant k at the pivot point. This system is similar in appearance to a scissor jack used to change tires on a car. In this case, the arms of the linkage (equivalent to the rods in this system) are entirely vertical,...

The transfer function is a fundamental concept representing the ratio of two polynomials. The numerator and denominator encapsulate the system's dynamics. The zeros and poles of this transfer function are critical in determining the system's behavior and stability.
Simple poles are unique roots of the denominator polynomial. Each simple pole corresponds to a distinct solution to the system's characteristic equation, typically resulting in exponential decay terms in the system's...
